Tb all whom #may concern: e

Be it known that I, FREDERICK W. JOHN- soN, a citizen ofthe UnitedStates, residing at Excelsior in the county of Hennepin and State ofMinnesota', have invented certain new anduse'ful; Improvements in Water-Motors; and I do hereby declare the following to'be a full, clear, andexact description of the invention, such as willl enable others skilledinthe art to which it make and use thev same.

kll/fy invention has for its object to provide an improved water motorvorpower d evice 2 'adapted to be operated'by a stream of runverticalsection taken on the line' wf' at" of Fig. 3'.

The water which actuates the motor is, as shown, delivered thereto byasluice trough l', having at its `delivery end adischarge passage 2,-t-hat o ens downward through the bottom thereof? In the vsluice1','islavertically adjustable gate byfmeas of which,

the amount of the currentflow maybe regulated. Located below the sluice1l is a receiving sluice 4, which, as shown, is alsol in the form=of atrough, and which extends under the former to a point considerably'backof its dischar e passage 2. AL transverse rock shaft 5 is gournaled'insuitable bearings on the sides of the sluice 4, and is located directlybelow the discharge passa e 2 of the sluice 1.- Tol the rock shaftb., aong'oscillatory sluice box -6- is rigidly secured' its central orintermediate portion. The' ends of' this sluice box are open, and'thebox isv providedat its centralj pFrtion-with a divid ing rib orpartition 7. hel open .ends of the boX- 6 work without frictionybut in'close engagement with the inner surfacesof the curved baile plates 8Aand 9. These baie plates 8 and 9, at their lower edges, terminateconsiderably above the `bottom of the appertains to e l different powerof utilization of more or less sluice 4.. The plate 9 is spaced from theend pl'a'te or head of the sluice, so as to form al water' accumulationchamber 10. A vertically adjustable gate 11 is mounted in suitableguides located below and spaced apart 'froin`;`the lower bathe plate 8.Bothof the bathe plates 8 andl 9 are made vertically adjlistable, .so asto vary the time of escape of the water from the sluice box, or tootherwise properly set the device so that it will produce j ofthecu'rrent of a river or other stream.

A deecting plate 12 is arranged to vijlbrate below the discharge passage2 of the gupper sluice 1', and as shown, this is pro-v pivotallyconnected thereto at 13. ,ends, the said delectinfr plates 12 are videdwith depending vided' with' uplturned end portions that embrace thesides of the said sluice 1, andare At its pro fingers-14, that work yinthe perforationsof arch plates 15 rigidly secured to the sides of theintermediate portion' of the oscillatory 'sluice box 6. 'Thisarsrangeihent is such that when the sluice box .is in the positionvshown in Fig. v2, the deflectingplate 12 will direct the water dischargefrom' the passage 2, into the rear comp'artment of the said sluice box;but when the' said sluice box is inthe position lshow'n in Fig. 3, saiddeflecting plate'12 will deflect the water into the down stream com-;p'artment, of' the said' sluice box. Otherwise stated', this,deiiect'in plate, by movements of the oscillatory slulce box 6, will beoscilllated from one extreme position intov the other, and will alwaysbe set to deliver the water` into the raised compartment Vof the saidsluice box.

0n' its sides, the sluice box 6 is preferably provided' with rollers 16that are adapted to engage the. inner surfaces of the vertical wallsofthe lower sluice and thereby prevent spreading' of the free end sideportions of i the said sluice box, and at the same time preventing' muchfriction between the said sluice box and lower sluice.

tone end, the rock shaft y5' is shown as provided with an arm 17 towhich the crank rod' 18 is attached for the purpose of trans Iittin'gmotion from the oscillatory. shiee box; to any malchine or mechanismwhich 1s to' be driven' thereby. it will; of' course, be

understood; that any suitablekind of powerv transmission mechanism' maybe used to transmit power from the said oscillatory sluice box.

The operation of the device is substantially as follows: When the sluicebox is in the position shown in Fig. 2, the water will, as beforestated, be delivered into the upstream compartment thereof, to-wit, intothe right hand compartment as shown in said view, and when the weight ofthe accumulated water is sutlicient to overcome the resistance ofthemechanism which is driven therefrom, this right hand end of the saidsluice box will be forced downward and the sluice box will then assumethe position shown in Fig. 3. The water discharged` by this downwardmovement of the right hand end of thesluice box will run chiey into thecompartment l0, but some thereof .will escape andrun downward into thelower sluice 4. The water. will then be directed by vthe deflectingplate l2 into the lefthand or downstream compartment of the sluice box,and when it has sufficiently accumulated therein, the said sluice boxwill be forced backv into the position shown in Fig. 2. While this istaking place, however, most of the water will escape from theaccumulation chamber or compartment 10, and will run downward into thesluice 4:. The accumulation of water in the chamber 10 vand the escapethereof, will take place iny part while the` moving end of the sluicebox from striking a hard blow on the bottom of the sluice. In the mannerabove described, it is evident, that under the flow of the .stream ofwater acting thereon, the sluice box so-called, will be kept undersubstantially an even oscillatory movement.

The device may, of course, be made of any desired size. It is especiallyadapted for use in connection with a running stream in the vicinity ofrapids, falls or a dam, but it may be installed in a stream having `butvery little incline, in which case, of course, the upper sluice wouldhave to be run a proper distance up-stream to obtain the vnecessary head.or fall of water from the one sluice box to the other at the placewhere the water is delivered into the so-called oscillatory sluice box.When made in large dimensions, the sluices will be preferably made ofconcrete reinforced with steel, and the sluice box should preferably beof steel. The bot-- tom of the receiving end of the lower sluice shouldbe preferably set at lthe high water line of the stream, so that itwould remain in operation under all conditions of the Water.v Y

. The rapidity of operation of the sluice. box may be controlled to alarge extent, by adjustments of the gate 3 of the upper sluice,

and the gate 11 in the lower sluice, should be correspondingly adjust/edso as to hold back enough of the water to aiford a cushion to thedownwardly moving ends ofthe oscillatory sluice box.

What I claim is:

1. In a device of the kind described, the combination with an uppersluice and a lower sluice, ofan intermediately pivoted oscillatorysluice box having an intermediate partition and open ends, said lowersluice having curved baiile plates curved on lines concentric to theaxis of the pivot of the oscillatory sluice box closely engaging andcoperating with the open ends of said oscillatory sluice box, andprovided with vdischarge passages at their lower edges, substantially asdescribed.

2. In a device of the kind described, the combination with an uppersluice and a lower sluice, of an intermediately' pivoted sluice boxhaving a central partition and open ends, curved bvaile plates in saidlower sluice cooperating with the open ends of said sluice box, andterminating above the bottom of said sluice, said lower sluice having anaccumulation chamber in its up-stream end beyond 'the uppermost of saidcurved battle plates, and a vibratory defiecting plate arranged todeliver water from said upper sluice always into the raised compartmentof said vsluice box, substantially as described. I

3. In a device of the kind described, the combination with lan uppersluice and a lower sluice, the former having a discharge passage in thebottom of its delivery end overan oscillatory sluice box intermediatelymounted on a pivot, located in said lower sluice below the dischargepassage of said upper sluice, said sluice box havingl a centralpartition and open ends, a pivoted .deflecting plate connected to andoperated by said sluice box, and arranged to deliver'4 the water alwaysinto the raised compartment of said sluiceybox, curved baille plates insaid lower sluice' cooperating with the open ends vof said sluice boxand terminating above the bottom of said lower sluice, said lower sluicehaving an accumulation chamber in its upstream end, and adjustable gatesone located in said upper sluice above the discharge passage thereof,and the other located inv said v lower sluice below the lower bailleplate, sub-I stantially as described.`
